Invasive Pacu Fish Caught In Concho River In Texas—Why Do People Need To Keep Flesh-Eating Fish And Killer Pythons?

The Facebook page of the Texas Department of Parks and Wildlife reports that a Pacu fish was caught recently in the Concho River near San Angelo.

Above you see the Pacu that was caught.

A Pacu is a flesh-eating freshwater fish that should be living in South America where it belongs.  The Pacu is a relative of the Piranha.

Her are some facts about this fish.

Here are facts and some history of the Concho River.

Here is how the San Angelo Standard-Times reported the capture of this fish.

The person who caught this fish had been looking to catch catfish.

The Pacu is an invasive species that messes up natural ecosystems. People illegally dump these fish into streams and rivers. A lot of folks just have no sense.

The Federal Department of Agriculture has a National Invasive  Species Information Center. 

These efforts will continue so long as we don’t slash federal spending to the bone as part of the Ayn Rand budgeting advocated by Mr. Romney and Mr. Ryan.

We can have our rivers filled up with flesh-eating fish to go along with all the Pythons now slithering about the U.S.

Of course the core issue is our fellow citizens who feel they need to keep killer fish and killer snakes as pets, and then–shockingly–find that they can’t manage keeping such creatures.

So they just let them loose on the rest of us.

I’d suggest to people that they read a book or take up a model train hobby instead of inflicting killer creatures upon the nation.

If Only We Could Communicate With Zebra Mussels

The Zebra Mussel is an invasive species clogging up American waterways.

Above you see a picture of a Zebra Mussel.

An excellent book about invasive species is called Out Of Eden–An Odyssey of Ecological Invasion by Alan Burdick.

Here is an overview of the Zebra Mussel issue and below is a portion of that overview– 

A small freshwater mollusk called the zebra mussel (Dreissena polymorpha), has been steadily invading America’s rivers and lakes. Zebra mussels originated in the Balkans, Poland, and the former Soviet Union. They first appeared in North America in 1988 in Lake St. Clair, a small water body connecting Lake Huron and Lake Erie. Biologists believe the zebra mussels were picked up in a freshwater European port in the ballast water of a ship and were later discharged into the Canadian side of Lake St. Clair.

Zebra mussels get their name from the striped pattern of their shells, though not all shells bear this pattern. They’re usually about fingernail size but can grow to a maximum length of nearly 2 inches. Zebra mussels live 4 to 5 years and inhabit fresh water at depths of 6 to 24 feet. A female zebra mussel begins to reproduce at 2 years of age, and produces between 30,000 and 1 million eggs per year. About two percent of zebra mussels reach adulthood.

Young zebra mussels are small and free swimming, and can be easily spread by water currents. Older zebra mussels attach themselves to hard surfaces by an external organ called a byssus, which consists of many threads. The mussels may attach to boats, pilings, water-intake pipes, and other hard surfaces, as well as to crayfish, turtles, other zebra mussels, and native mollusks. While zebra mussels can attach themselves securely, they may also move, and can reattach themselves easily if dislodged by storms.

Zebra mussels upset ecosystems, threaten native wildlife, damage structures, and cause other serious problems. Millions of dollars are spent each year in attempting to control these small but numerous mollusks.

Below is a photo of many Zebra Mussels in Lake Michigan.

Here is information about Zebra Mussels in the Great Lakes region.

Here is Sea Grant’s National Aquatic Nuisance Species Clearinghouse.

In the early 1990’s, I took a tour of the main plant of the Cincinnati Waterworks.

The man giving the tour, an official with the water works, talked about the threat of Zebra Mussels plugging up the water intake pipes.

I said to him ” If only we could communicate with them.”

I thought it was a funny enough line.

The waterworks man did not appear to think it was funny. 

Here is the link to the Cincinnati Waterworks. You can click under features on the right of homepage for a history of the waterworks.
